WILLIAM J. TRIPP, OF NEW YORK, N. Y.

ROLLER-BEARING FOR CAR-JOURNALS.

SPECIFICATION forming part of Letters Patent No. 587,248, dated July 27,1897.

Application filed October 24, 1896. Serial No- 609,880. (No model.)

T0 on whom it may concern:

Be it known that 1, WILLIAM J. TRIPP, of New York city, in the countyand State of New York,ha-ve invented a new and Improved Roller-Bearin gfor Car-Journals, of which the following is a full, clear, and exactdescription.

The object of the invention is to provide a new and improvedroller-bearing for carjournals which is completely dust-proof, arrangedto reduce friction to a minimum to insure long life to the severalparts, and adapted to readily take up all end thrust of the axle.

Theinvention consists principally of a box, a thrust-cap on the end ofthe journal, and rings in the said box and forming with the saidthrust-cap a ball-race for the balls.

The invention also consists of certain parts and details andcombinations of the same, as will be fully described hereinafter andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a partofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a sectional plan view of the improvement on the line 1 1 ofFig. 2. Fig. 2 is a sectional front view of the same on the line 2 2 ofFig. 1, and Fig. 3 is a side elevation of a ball-section.

On the car-journal A is loosely held a collar B and a cap 0, bothextending into a box D, held on the car-truck in the usual manner andclosed at its outer end, as plainly indicated in the drawings. In thisbox D are arranged a series of rings E E E in alinement with one anotherand with the outer face of the outer ring E resting against a projectionD, formed on the inside of the box D, so that this ring E is preventedfrom moving outwardly.

' In the peripheries of the collar B and the cap 0 are formed annularV-shaped grooves B and C, respectively, which form, with the bevelededges of the corresponding rings E E E ball-races for the balls F,preferably journale-d on transversely-extending axes F, held inring-sections F as plainly indicated in the drawings. The inner end ofthe box D is adapted to be closed by a cover G, preferably screwing inthe said box and formed with a toothed flange G, engaged by alocking-pawl G pivoted on the inner end of the box D, the saidpawl-serving to lock the said cover in place after the latter is screwedin position on the inner end of the box D. The cover G is adapted toengage the inner face of the innermost ring E, so that when the cover isturned the said ring is adjusted lengthwise in the box and by the ballsF insures an adjustment of the rings E and B, as well as of the cap 0.

The cover G is ring-shaped and is formed with an inwardly-extendingannular flange G through which passes the journal A and on which abuts awasher H, of suitable material and held to the flange by an L-shapedring I, pressed on by a spring J, resting against a similar ring I,fitted on the under side of a plate K, bolted orotherwise fastened tothe cover G. The ring I fits close upon the journal A, next to the axleA, so that the cover G is completely dust-proof, and consequentlyvthebox D and all its contents are rendered dust-proof, owing to the boxbeing closed on the outer end. Now it will be seen that by thearrangementdescribed the collars B and .G are free to revolve on thejournal A and are also free to slide on the said journal, to-

gether with the rings E E, so that any Wear between the balls and thesurface of the ballrace can be readily taken up'by the operator screwingup the cover G. It will further be seen that as the collar C is in theform of a cap fitted upon the end of the journal the said cap will takeup any thrust of the axle, owing to the balls F and the ring E beingheld against outward movement in the box D by abutting against theprojection D.

It is understood that I do not limit myself to balls journaled on axesheld in sectional rings, as it is plain that loose balls may be used inthe ball-races formed between the collar B, the cap 0, and the rings E EE Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1.-A roller-bearing for car-journals,comprising a box, a thrust-cap on the end of the journal, and rings inthe said box and form: ing with the said thrust-cap a ball-race for theballs, substantially as. shown and described.

3. A roller-bearing for car-journals, com-' prising a box, a ring heldin the said box against outward movement, a second ring adjacent to thefirst-named ring, and a thrustcap held on the end of the journal andfOl'llling With the said rings a ball-race for the balls, substantiallyas shown and described. I

4. A roller-bearing for ear-journals, comprising collars held on thejournal, a series of rings forming ball-races With the said 001- lars,the outermost ring being held against movement, the remaining ringsbeing free to move toward the outer ring, balls held in the said races,and sectional rings carrying pivots for the balls to turn on,substantially as shown and described.

5. A roller-bearing for car-journals, comprising a box closed at theouter end, a ring held in the closed end of the said box, a series ofrings in alinement with the said outer ring, a collar and a thrust-capheld on the journal and forming ball-races with the said rings, a set ofballs for each ball-race, and an adjustable dust-cap held on the innerend of the box and engaging the innermost ring, to adjust the severalrings in their relation to each other and to the balls, substantially asshown and described.
